The border suggestion is really nice. I think that would encourage more fighting as I could visually see what my neighbors own, and if they are in fact encroaching on my area.
Yes to orbital miners!
While I’m not happy with Syntis getting a form of corruption (interference), if capitals would allow us to potentially have more than 45 planets, that would be nice. Perhaps we can colonize 45 systems? That would make systems with large numbers of planets more valuable for high-population systems. Or keep it that each capital allows us to get more planets. Whatever allows colonization of unlimited worlds. Yes, that would get a little taxing on the servers, but it would make for much more interesting and varied gameplay.
